Trumpet fanfares have long been used in ceremonies, theatre and television to signal an important arrival, and short recordings of them became popular as downloadable sound effects for videos, streams and memes. On soundboards they sit alongside other loud, instant attention-grabbers such as the MLG air horn, all used to turn a reveal into a joke or a celebration. The appeal is simple: everyone recognises the brass call immediately, so creators can announce a person, a prize or a punchline in under two seconds without any explanation.
